Answer:
The correct answer is "[tex]x=\frac{1}{4}[/tex]" and "[tex]y=-\frac{1}{2}[/tex]"
Step-by-step explanation:
As we know,
y = -2x ...(equation 1)
y = 2x-1 ...(equation 2)
On putting the value of "equation 1" in the "equation 2", we get
⇒ [tex]y=2x-1[/tex]
⇒ [tex]-2x=2x-1[/tex]
On adding "2x" both sides, we get
⇒ [tex]-2x+2x=2x-1+2x[/tex]
⇒ [tex]0=4x-1[/tex]
⇒ [tex]4x=1[/tex]
⇒ [tex]x=\frac{1}{4}[/tex]
Now,
On putting the value of "x" in equation 1, we get
⇒ [tex]y=-2x[/tex]
⇒ [tex]y=-2\times \frac{1}{4}[/tex]
⇒ [tex]y=-\frac{1}{2}[/tex]
Determine the values of the unlabeled parts of the triangle.
OA) ZQ = 63.4°, PQ = 1.84, QO = 4.47
OB) ZQ = 26.6°, PQ = 2, QO = 5.12
OC) ZQ = 63.4º, PQ = 2, QO = 4.47
D)
ZQ = 63.4°, PQ = 1.84, QO = 5.12
Answer:
∠Q = 63.4º, PQ = 2, QO = 4.47
Step-by-step explanation:
A triangle is a polygon with three sides and three angles. There are different types of triangles such as the equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.
Triangle POQ is a right angled triangle because ∠P = 90°. Also, ∠O = 26.6°.
Therefore in ΔPOQ: ∠P + ∠O + ∠Q = 180° (sum of angles in a triangle).
90 + 26.6 + ∠Q = 180
∠Q + 116.6 = 180
∠Q = 180 - 116
∠Q = 63.4°
We can find PQ and QO using sine rule. Sine rule for ΔPOQ is given as:
[tex]\frac{PO}{sin Q}= \frac{PQ}{sinO}= \frac{QO}{sin P}\\\\Finding\ PQ :\\\\\frac{PO}{sin Q}= \frac{PQ}{sinO}\\\\\frac{4}{sin(63.4)} =\frac{PQ}{sin(26.6)}\\\\PQ= \frac{4}{sin(63.4)} *sin(26.6)\\\\PQ = 2\\\\Also\ finding\ QO:\\\\\frac{PO}{sin Q}= \frac{QO}{sinP}\\\\\frac{4}{sin(63.4)} =\frac{QO}{sin(90)}\\\\QO=\frac{4}{sin(63.4)} *sin(90)\\\\QO = 4.47[/tex]

Martina wants to earn more than $80 selling ice cream cones from her ice cream truck. She already earned $24 selling ice cream cones. The price of each ice-cream cone is $2. If x represents the number of ice cream cones to be sold, which statement represent how many ice-cream cones Martina needs to sell to earn more than $80?
(Show some work lol)
Answer:
28 icecream cones
Step-by-step explanation:
80-24=56. 56÷2=28
(28×2=56)
1.) Find out the distance covered when, speed is 960 km/hour and time is 1 hour 50 minutes.
2.) If distance travelled by a train is 495 km in 4 hours 30 minutes, what is its speed?
3.) A man runs at the speed of 10 km/hr. How much time will he take to cover 750 metres?
4.) Aaron ran 500 metre in 100 Seconds. Find the speed in km per hour.
5.) A cyclist travels at a speed of 20 km/hour. How far will he travels in 50 minutes?
Answer:
A: 1070 m
Solution:
based on the formula :
960km/h= x (the distance) / 1h50m
Answer:
Step-by-step
The rate of change is 150 km per minute.
The rate of change is 2.5 km per second. explanation:
Identify the domain and range, then evaluate each function for the given value of x.
(I do not need much help for the domain and range but mostly the "Find f(5)"
Answer:
See below
Step-by-step explanation:
Domains are the first values and range are the second values given in the brackets.
Domain = {10, - 2, 5, 3}
Range = {7, 4, 3, 10}
I the third bracket, at x = 5, y is 3.
So,
f(5) = 3
Jazel time to check your progress. So far you have completed 816 miles which is 47% of the trail. Can you find about how many miles for the total trip?
Answer:
1,736.17miles
Step-by-step explanation:
Let the total trip be x miles
If 47% of the total trip is 816, then;
47% of x = 816
0.47x = 816
Divide both sides by 0.47
x = 816/0.47
x = 1,736.17miles
Hence the total miles for the trip is 1,736.17miles

Step-by-step explanation:
Three siblings are participating in a family-friendly running event. - The oldest sibling begins at the start line of the race and runs 7 miles per hour the entire time. - The middle sibling begins at the start line and walks at 3.5 miles per hour throughout the race. - The youngest sibling joins the race 4 miles from the start line and runs 5 miles per hour the rest of the way.
The siblings walking or running at a constant rate, illustrates a linear function.
The graph of the oldest sibling is Graph B The graph of the middle sibling is Graph CThe graph of the youngest sibling is Graph AThe complete question requires that, we match each graph to the sibling (see attachment)
Oldest sibling
[tex]Starts = 0[/tex] --- start line
[tex]Rate =7[/tex]
So, the equation is:
[tex]y = Starts + Rate \times x[/tex]
[tex]y = 0 + 7 \times x[/tex]
[tex]y = 7x[/tex]
When [tex]x = 1[/tex]
[tex]y = 7 \times 1 = 7[/tex]
This means that;
The graph of the oldest sibling passes through [tex](1,7)[/tex]
The graph of the oldest sibling is Graph B
Middle sibling
[tex]Starts = 0[/tex] --- start line
[tex]Rate = 3.5[/tex]
So, the equation is:
[tex]y = Starts + Rate \times x[/tex]
[tex]y = 0 + 3.5 \times x[/tex]
[tex]y =3.5x[/tex]
When [tex]x = 1[/tex]
[tex]y =3.5 \times 1[/tex]
This means that;
The graph of the middle sibling passes through [tex](1,3.5)[/tex]
The graph of the middle sibling is Graph C
So, we can conclude that:
The graph of the youngest sibling is Graph A

Let the required mass be x.
As we know that 1kg is equal to 1000g.
So equation can be made as following:-
350g+x=1000g
➛ x=1000g-350g
➛ x=650g

Which of the following illustrates the truth value of the given conditional statement?
p. 10<7
q. 10 <5
~p -> ~q
Answer:
~p -> ~q
Step-by-step explanation:
A conditional statement in logic may be symbolized by the alphabets, p and q, It always contains an if - then statement.
There is always a logical connector in the statement with the symbol ->.
A conditional statement is false if the hypothesis is true and the conclusion is false.
The statement in the answer above reads in word; "if not p then not q".
